1 Aerospike Databases部署前准备工作

尽量不要对ssd做RAID，RAID控制器会带来不必要的延迟
如果必须做RAID，建议每块盘单独做RAID0。如果做了RAID，需要利用 LSI Mega CL 进行一些优化设置。参考：LSI Mega CLI: [[http://www.aerospike.com/docs/operations/plan/ssd/lsi_megacli.html]]
SSD硬盘不需要格式化，不需要挂载，直接attach到服务器母板上，Aerospike把SSD当raw disk使用。
有些SSD需要预留部分空间给驱动控制器使用，这样能带来更好的性能。

对于intel CD S3500的SSD，Aerospike强烈建议进行分区，第一个分区79%，第二个分区21%。
使用第一个分区进行后面的ACT测试

SSD硬盘在第一次使用之前需要做清零操作，清零操作会清除SSD硬盘硬盘中的数据。新添加SSD硬盘对数据库存储容量进行扩容时，只需要对新添加的SSD硬盘做清零操作（参照下面信息进行清零操作）。

sudo dd if=/dev/zero of=/dev/<deviceID> bs=1M&

出现提示：No space left on device or an out of space error 说明硬盘清零操作完毕。

2 Aerospike Databases部署步骤

依赖环境安装

sudo yum install openssl-devel
sudo yum install gcc gcc-c++

server端安装步骤

wget -O aerospike.tgz 'http://aerospike.com/download/server/latest/artifact/el6'
tar -xvf aerospike.tgz
cd aerospike-server-community-*-el6
sudo ./asinstall # will install the .rpm packages
sudo service aerospike start
sudo tail -f /var/log/aerospike/aerospike.log | grep cake

wait for it. "service ready: soon there will be cake!"

关闭Aerospike Databases节点机器之间的防火墙
参考下面配置，修改Aerospike Server端conf文件。

service {
user root
group root
paxos-single-replica-limit 1 # Number of nodes where the replica count is automatically reduced to 1.
pidfile /var/run/aerospike/asd.pid
service-threads 32
transaction-queues 32
transaction-threads-per-queue 3
proto-fd-max 100000
fabric-workers 96
microbenchmarks  true
}

logging {
# Log file must be an absolute path.
file /var/log/aerospike/aerospike.log {
context any info
}
}

network {
service {
address any
port 3000
}

heartbeat {
mode multicast
address 239.1.99.222
port 9918
#interface-address 192.168.1.116

# To use unicast-mesh heartbeats, remove the 3 lines above, and see
# aerospike_mesh.conf for alternative.
#
#mode mesh

#mesh-seed-address-port 192.168.1.116 3002

#mesh-seed-address-port 192.168.1.117 3002

interval 150
timeout 20
}

fabric {
port 3001
}

info {
port 3003
}
}

namespace test {

}
}

启动Aerospike Databases

sudo service aerospike start 或者 sudo  /etc/init.d/aerospike  start
